Hi all, I have purchased 8 pieces of solar panels as enclosed and would like to know the connection in series whether there is a need to have diode wired with them. Grateful for your professional advice, much appreciated.
No need for a diode in series. Almost all modern solar panels already contain bypass diodes. Some cheaper panels may not, though.
When connecting panels in series, just be careful you do not exceed the input voltage of the inverter or MPPT. Always, use a string voltage calculator to check.
